A $51 million modification of the Chemical Waste Treatment Centre at Tsing Yi has been recommended to get rid of waste from hospitals, clinics and laboratories.
In a submission to lawmakers, the Government has stuck to its proposal to dispose of clinical waste by incineration, despite concern over emissions.
About eight tonnes of clinical waste, including needles and human organs, is dumped in landfills each day without being treated.
The Environment and Food Bureau said other disposal methods might also pollute the environment.
It recommended burning the material at the Chemical Waste Treatment Centre as a medium-term solution. It also remained open to the option of installing an 'alternative treatment facility'.
Despite the emission of dioxins from burning chemical and medical waste, officials maintained incineration was the most common disposal method in the US, Europe, Canada and Japan.
